Answer 2

♧♧HERE IS YOUR ANSWER♧♧

We have to find the four digit numbers (>999 and <3000).

We make an AP :

1000 + 1001 + ... + 2998 + 2999

First term = 1000

n-th term = 2999

Common difference = 1

We know that :

The n-th term = First term + (n - 1)×(common difference

=> 2999 = 1000 + (n - 1)×1

=> n - 1 = 1999

=> n = 2000

Therefore, there are 2000 four digit numbers between 999 and 3000.
